HAND S CUDDI NG BEAM Filed Jan. 23, 1932 INVENTOR l\TTORNEY Patented Oct. 10, 1933 UNITED STATES iPATENT OFFICE 2 Claims.

This invention relates to hand scudding beams.

The principal object of this device is to provide a structure upon which is placed raw hides which are scraped in the process of preparing for tanning.

A further object of this device is to provide a pad for a scudding beam which is iinpervious to lime water and which is soft and yielding to pressure of a scraping blade.

A further object is to provide a pad which is permanent and not necessary to be built up each day.

A still further object of the invention is to provide a yielding layer such as sponge rubber to back up a surface layer of tough rubber in order that the scraping process may be more accurately and rapidly performed.

It has been the custom in tanning leather to remove the remaining hair from the hides after various dehairing operations have taken place. In order to do this a wet hide is taken from a lime water vat and placed upon a scudding beam. In this operation the hide is placed hair side up on this scudding beam and a large curved blade with a handle on each end is used to scrape any remaining hair and substances adhering to the sur-faces of the hide. It has been the practice in. preparing hides in this way to use a scudding beam without any padding and in the beginning of the operation commonly used a hide is placed on a scudding beam and scraped. This method is objectionable in that the hide rests upon an unyelding surface and prevents rapid as well as accurate work in scraping the hide. In order to overcome some of the undesirable conditions in a scudding beam of this nature it has been the practice to allow the first hide and others so scraped to remain upon the scudding beam in order to build up a pad. After this wet hide pad U is built up the balance of the hides are scraped and removed for further operations.

At the end of the working day the hides comprising the pad have become air-blasted" on all the exposed edges due to the action of oxygen in the air in contact with lime on the wet hide. This air-blasting together with the imperfect scraping of the lower hides on the pad causes an inferior quality and the entire pile so air-blasted is removed at the end of the working day and marked as second grade leather.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being lthere is provided a scudding beam 1.

- moisture.

understood that changes in the precise embodiment ofthe invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompany-l 69 ing drawing, whereimo Figure l is a perspective View of the device.

Figure 2 is a side elevation of the device;

Figure 3 is a partial end view of the device with parts broken away.

Figure 4 is a partial cross section taken on line 4-4 of Figure 3.

By referring to the drawing it will be seen that This scud-V ding beam 1 is provided with legs 2 and 3. referring to Figures 3 and 4 it Will be seen that the scudding beam 1 is provided with an elastic covering 4 preferably made of rubber. The inner part of this covering 4 is desirablyV constructedof sponge rubber with an outer layer impervious to In placing this covering at upon the scudding board 1 it has been found that by subjecting the covering 4 to heat in order to expand the same and then placing it upon the scudding beam 1 the natural contraction draws the covering 4 tightly over the scuddng beam l. `In order to hold this covering 4 so as to protect the sponge rubber andhold it in a stretched position there is provided a pair of clamp strips 5 which hold down-turned edges of the covering betweenthe 55 clamp strips 5 and under surface of the scudding beam l.. Theseclamp strips 5 are held in position by suitable lugs 6. It will also be seen that the extreme edge 7 of the covering 4 is nailed down to the clamp strips 5 by means of nails 8.

What I claim isz- 1. In a device of the class described, an inclined scudding beam,. a pair of legs for said inclined scudding beam, a covering for said scudding beam comprising an under layer ofsponge rubber, an 95, outer layer of moisture resisting rubber for the purpose of forming a yieldable surface lupon which to scrape hides, substantially as described.

2. In a device of the class described, an inclined and curved scudding beam, a pair of legs for said inclined and curved scudding beam, a covering for said scudding beam comprising an under layer of sponge rubber, an outer layer of moisture resisting rubber for the purpose of forming a yieldable v surface upon which to scrape hides, a pair of clamp strips for the purpose of holding said covering in a stretched position, means forholding said clamp strips to said scudding beam, substantially as described.
